摘要： A system for finding black spots in a separator includes a winder, a rewinder that takes out and winds a separator from a rechargeable battery cell and supplies a sample of the separator; a foreign material remover that removes a foreign material from the separator; an image measurer that obtains a first image where black spots are estimated in the separator passing through the foreign material remover with a first camera and records the position of the first image; a second image measurer that selects where black spots are estimated and acquires an image of black spots and foreign material other than black spots recorded by a second camera by using the first image for the separator passing through the measurer; and a black spot sorting unit displaying the position after secondarily selecting black spots by deep learning the first image and the second image with a deep learning software.
